Endoscopic measurement of lesion size:An unmet clinical need

In recent years,the field of endoscopy has experienced significant technological advancements.These developments have facilitated the efficient use of endoscopy for precise examination and minimally invasive treatment of various lesions.A key parameter considered during both endoscopic diagnosis and treatment is the size of the lesion.In colon polypectomy,the size of the polyp is linked to the probability of malignancy and the likelihood of complications.Similarly,in the case of early gastric cancer,larger tumors are often associated with an increased likelihood of lymph node metastasis,and whether to perform endoscopic submucosal dissection(ESD)is partially dependent on the size of the lesion.Therefore,accurate measurement of lesion size may significantly impact the diagnosis and treatment plan for the patient.However,at present,there is no standardized method for quantitative measurement during endoscopy.This lack of a universal technique hinders the ability of clinical guidelines to provide precise recommendations for treatment.
